The essential ingredients of the solution are (A) a resinous compound such as an acrylic resin and (B) a crosslinking compound such as a triazine compound which are combined in such a proportion of 2:8 to 4:6 by weight that the overall weight-average molecular weight of the components (A) and (B) is in the range from 1300 to 4500. This inventive coating solution is advantageous in a respect of evenness in the thickness of the coating layer even on a patterned resist layer having a crowdedly hole-patterned area and an isolatedly hole-patterned area and absence of unfilled voids within the hole patterns.Type: ApplicationFiled: December 11, 2001Publication date: June 20, 2002Inventors: Etsuko Iguchi, Jun Koshiyama, Kazumasa Wakiya
